Abstract
The present invention relates to a photocurable adhesive composition. The photocurable adhesive composition comprises a urethane (meth)acrylate resin, a functional-group-containing polybutadiene, a photocurable monomer and a photoinitiator; and the functional group is either an epoxy group or a hydroxyl group. The photocurable adhesive composition ensures good outdoor readability, has outstanding adhesive properties and impact strength and optical transparency and minimises the phenomenon whereby substantial contraction occurs during photocuring, and thus can suitably be used for a display.
Description
Technical field
The indicating meter that the present invention relates to Photocurable adhesive composition and comprise this Photocurable adhesive composition.Particularly, the indicating meter that the present invention relates to Photocurable adhesive composition and comprise this Photocurable adhesive composition, wherein this Photocurable adhesive composition comprises specific binding agent to improve outdoor visibility meter and shrinking percentage, guarantees the superperformance aspect adhesive power, optical transmittance and shock strength simultaneously.
Background technology
Conventionally, mobile display can be divided into for the indicating meter of mobile telephone and for the indicating meter of TV and watch-dog.For this display pannel, important problem is to improve outdoor visibility meter and shock strength to meet the increase of panel size.In this, optical adhesive film is used to improve outdoor visibility meter and shock strength.
Display pannel comprises as outermost glass port layer, is placed in the gas cloud under described glass port layer and is placed in the ito glass under described gas cloud.Described gas cloud fills to improve outdoor visibility meter with the transparent material with the specific refractory power similar to window glass.
At present, the material as optical adhesive is divided into liquid-type and membranous type material.Although easy to use, membranous type material is difficult to be applied to various structures and remove the bubble producing when adhering to substrate.And, therefore because membranous type material has high internal cohesion and is difficult for removing, described membranous type material have bad can re-workability and produce by complicated process, cause manufacturing cost to increase.
Therefore the development of cheap liquid phase material that, allows to be easy to remove bubble is in the development trend that is recent this area.This liquid phase material forms film by photocuring.By filling substrate in liquid-type tackiness agent, with liquid-type tackiness agent described in posterior photocuring, and make liquid-type tackiness agent form film.Although this liquid-type tackiness agent can make bubble be easy to remove, and has the problem of high shrinkage when photocuring.In addition, typical liquid phase adhesive composition has the high acid value that is less than pH4, thereby causes substrate corrosion.
And, along with the ever-increasing recent development trend of mobile display size, the adhesive power therebetween being brought by contraction during due to photocuring deteriorated, photo-curing material is often for example, with material (glass, polycarbonate or polymethylmethacrylate) above separated.Particularly, as the isoprene or the butadiene resin that can be applicable to the elastomeric material of indicating meter, after photocuring, aspect increasing adherence, there is limitation.In addition, along with the increase of display product size, exist having than the more low viscous material of typical material so that fluent material more effectively disperses.
Summary of the invention
